Once Upon a Mix-Up (Full House: Sisters)

Stephanie is selling jewelry at a thrift sale to benefit underprivileged kids. Totally cool -- except when she realizes she accidentally sold a valuable antique necklace -- for twenty-five cents!

Stephanie promises that one way or another she'll get it back. But can she find the necklace -- or is it lost forever?

Michelle's fourth-grade class is performing Cinderella -- and Michelle is the star! Too bad the boy who is playing Prince Charming is a terrible actor.

No sweat. Michelle has a plan! She's going to help Prince Charming by practicing with him -- all the time. There's only one problem: Michelle doesn't realize that once she puts her plan into action, it's going to backfire in a way she never expected!
